Passive Infra-Red (PIR) sensor is a pyroelectric devices motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can detect by checking for a high signal on a single I/O pin. Usually used as a security device in a monitored area (such as a room or hall) to detect appearance of human.
